Abstract
PURPOSE:To control the timing of ignition properly in accordance with various parameters of the engine by using charging and discharging circuits wherein charging and discharging currents change according to a voltage selected selectively in accordance with the parameters of the engine. CONSTITUTION:Starting from a reference crank angle M, discharge is made by a current i2, and when the voltage comes to a prescribed level, an ignition signal is generated. Further by a current i1 charge is made. The currents i1 and i2 change according to the voltage Vr selected selectively in accordance with the parameters of the engine. When Vr increases, i1 becomes large and i2 small. Therefore, the timing of ignition is changed in accordance with the parameters of the engine. Fixed angle characteristics at the rise and end are obtained by making the control voltage Vr fixed. By this constitution, the timing of ignition which is optimum for the demand of the engine is obtained.
